    Your fan should kick in around 90 degrees. S2 engine are made to run about this temps. If the temp stays down, the ECU will still think it is warming up. So you are waisting fuel.

    Maybe your switch or temp sensor is broken?

      Damn, my car have A/C, but I have a different problem......... my car start the low speed fun when I push up the interior temp, even if the AC its desconected or engine its cool............. Its natural to switch on the fan when the AC start to work in the winter to dehumidity the cockpit, but still work even if I manual desconected the AC........ it really pistme off


      Any Idea? Maybe im going to start to change all the damn electrics termostat!
